Solution Overview
Problem
Existing shaved ice machines suffer from low cold conduction efficiency due to a small contact area between the evaporation pipe and the barrel shell, resulting in inefficient heat transfer.
Innovation Solution
An ice-making assembly with an evaporation pipe wrapped by a cold conduction sleeve made of a cold conduction material, where only the inlet and outlet ends of the evaporation pipe are exposed, and a housing made of a heat conduction material, with a large contact surface area for enhanced heat conduction, along with a stirring mechanism to facilitate uniform cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the evaporation pipe is formed by winding a metal pipe through bolts, then the assembly is easier to manufacture, but the contact area with the barrel shell is small resulting in low cold conduction efficiency
Solution Approach 1:
The patent introduces a cold conduction sleeve as an intermediary component between the evaporation pipe and the barrel shell. This sleeve is made of material with high thermal conductivity and is in close contact with both the evaporation pipe and the barrel shell, serving as a mediator to transfer cold efficiently from the evaporation pipe to the surrounding structure, thereby resolving the poor thermal contact caused by the wound pipe structure.
Solution Approach 2:
The patent employs composite material structure by combining the metal evaporation pipe with a cold conduction sleeve made of different material properties. The sleeve material is specifically selected for its superior thermal conductivity characteristics, creating a composite system that enhances overall heat transfer performance while maintaining the structural integrity of the original pipe assembly.
2Device complexity
If the evaporation pipe is wound through bolts, then the structural assembly is simpler, but the flatness of the outer wall is poor resulting in point contact and low cold conduction efficiency
Solution Approach 1:
The cold conduction sleeve acts as a mediator that compensates for the poor flatness of the wound evaporation pipe. By providing a smooth, thermally conductive interface between the irregular pipe surface and the barrel shell, the sleeve ensures consistent thermal contact without requiring high manufacturing precision from the pipe winding process itself.
Solution Approach 2:
The patent changes the thermal conduction parameter of the system by introducing the cold conduction sleeve with superior thermal conductivity properties. This parameter change compensates for the geometric imperfections of the wound pipe, transforming the overall thermal performance from poor to efficient despite the simple assembly method.
